NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

PatentedDec. 30, 1913.

Application filed May 6, 1913. Serial No. 765,921.

To all whom it may concern Be it known that I, WALTER E. BLACK- srook, a citizen of the United States, residing at Astoria, in the county of Clatsop and State of Oregon, have invented new and use ful Improvements in Non-Refillable Bottles,

.of which the following is a specification.

The invention relates to bottles, and more particularly to bottles of the non-refillable type, and has for an object to provide a bottle body which cannot be conveniently refilled after the original contents have once been withdrawn therefrom.

The invention embodies, among other features, a non-refillable bottle which is simple in construction and which, upon being tilted, permits of the contents being readily poured therefrom, the said bottle being so arranged and constructed that it cannot be conveniently refilled with a spurious fluid after the original contents have been withdrawn therefrom.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a fragmentary vertical sectional view, showing the position of the valve when the bottle is in an upright position; Fig. 2 is a similar view showing the bottle tilted and the valve in open position; and Fig. 3 is a horizontal sectional view taken on the line 3-3 in Fig. 1.

Referring more particularly to the views, I provide a bottle body 10 including a neck 11, a valve seat 12 being formed on the bottle body at the point of formation of the neck 11, as shown, with a ball valve 13 arranged to slide within the neck of the bottle body and normally reposing on the said seat to close the exit of the bottle body. A plurality of longitudinal passages 14 are formed in the neck 11 and a seat 15 is formed within the neck, with a suitable stopper 16 reposing on the said seat, thus providing a chamber 17 in which the ball valve 13 is adapted to operate, it being understood that the passages 14 terminates in the chamber 17 and in a chamber 18 formed above the stopper 16. The stopper supports a plurality of inclined springs 19 projecting from the periphery of the stopper, the said springs being adapted to spring into notches 20 formed in the neck 11, when the stopper is initially placed in position within the neck. The upper end of the neck 11 is preferably flared to provide a seat 21 adapted to receive and support a cork 22 of the ordinary type.

In the use of the device described, the bottle body is first filled with the desired fluid, after which the valve 13 is dropped into the neck to close the exit from the bottle body and the stopper 16 is then placed within the neck and secured in locked position therein by pressing the stopper downwardly to repose on the seat 15, thus permitting the free ends of the springs 19 to spring into the notches 20 formed in the said neck to lock the stopper thereto. It will now be seen that the stopper 16 is interposed between the termini of the passages 14. Now if the bottle body is tilted, the ball valve 13 will gravitate into an open position and away from the seat 12, thus permitting the fluid in the bottle body to pass outwardly into the valve chamber through the passages 14 into the chamber 18, from which the fluid will pass out of the neck of the bottle, the cork 22 having been previously removed from the neck. It will be apparent that the stopper ,16 not only closes the main passage to the bottle body and constitutes a wall of the valve chamber 17, but the said stopper also acts as a means for limiting the movement of the valve 13 when the same is unseated and gravitates into open position upon the tilting of the bottle body.

From the foregoing description it will be apparent that the non-refillable bottle disclosed herein embodies few and simple parts which can be readily assembled and which further can be manufactured at a low cost.

Having thus described my invention, I claim:

In a non-refillable bottle, the combination with a bottle body including a neck of a stopper for insertion into a medial reduced portion of the neck to divide the interior of the neck into a plurality of chambers, one
